Our nightly autobuilds build on a lot of architectures, this includes
building and executing the test harness.
We have also found real bugs which could affect anyone but only showed
up consistenly on sometimes just one architecture. For example, I
recall one bug that only failed when running the test harness on Tru64
(non-C99 system). In other words, we need to be able to run the tests
on as many systems as possible because otherwise we may not find all
the bugs (bugs that can affect all systems. The point is that they may
be reproducible only on some systems. As developers typically use
either Linux or Windows systems we need the test harness run on every
_other_ kind of system).

So, my point is that we need to be able to compile and run the test
harness on non-modern systems exactly _because_ contributors will be
using a modern OS and compiler.
